I'm on a mac and all my issues with excel first started when I tried saving a sheet from a file that had special read/write permissions on (my document). After I copied over this sheet to a separate excel document/ blank sheet, I tried to save the new file as a new excel document. When I pressed "save as" and then "save" the entire save box turned grey and froze. It froze for an infinity amount of time and now whenever I try to save the document it freezes every time (also, it automatically does "save as" function regardless if you press command + s). I now have to force quit the document every time in order to get the frozen sheet to go away.
THEN I tried opening a totally separate file (new blank docs, other spreadsheets, etc.) on excel and now NOTHING--ZERO EXCE FILES- save properly. EVERYTHING freezes when I try to save it.
I went and checked for microsoft updates (because I have it set to manual check) and updated the latest versions/updates available.
STILL NOTHING SAVES. What else can I do? Any help would be super appreciated.
